Solar-System Bounds on the Aldred Frame: Perihelion Precession, Frame Dragging, and Light Travel Time
Year: 2026
Type: preprint
Abstract: In Einstein-Cartan spin-torsion gravity, torsion is algebraic and vanishes in vacuum, so the frame predicts the general-relativistic result exactly in Mercury's perihelion advance, in Lense-Thirring frame dragging (Gravity Probe B and LAGEOS), and in the Shapiro delay (Cassini, gamma-1 = (2.1 +/- 2.3)e-5): anomalous advance zero, frame-dragging anomaly zero, gamma-1 = 0. The only correction is the interior density renormalization Delta rho/rho = rho/rho_A with rho_A = 9.72e54 g/cm^3, whose largest value anywhere in the solar system, at the solar core, is 1.54e-53. Unabsorbed upper bounds fall short of the observational bounds by 49 to 65 orders of magnitude; a measurable anomaly would require densities of 2.24e50 to 9.72e53 g/cm^3 or spin densities 1e25 to 1e26 times those present. AI-use disclosure: the computation and drafting were performed by Dave, an AI system, under the author's direction; the author of record, William Alexander Aldred, has reviewed the manuscript and takes responsibility for its content.
